When a friend of mine bought his Corvette, he also stated that he would not take delivery on his car if it had a dealer sticker on it. Well after waiting for a month, he went to pick it up and sure enough, there was a sticker on it. He walked away and never signed the papers on it. The sales manager called him later and asked if there was a problem. My friend said that if they wanted him to buy the car, they had better knock off another 10k for advertising or get him another car without a sticker. He eventually went to another dealer who would never put a sticker on a Corvette.
